KDE/Xfce performance differences

Is there a noticeable CPU/RAM performance difference between
KDE or XFCE on the same machine?

XFCE has a ‘leaner’ reputation, I would say it is the same, but I guess you could see by yourself how both perform with a live USB from latest ISO releases.

They’re both fairly similar on resources theses days. Biggest differences are kde has far more customisation but also more bugs/quirks whereas xfce is pretty solid but not the options of kde

The guys above has mentioned they are the same in resources but in my experience xfce consumes less ram compared to kde

This was discussed previously. Have a look there.

@Thenujan that was a long time ago. Nowadays it’s just a question of taste and the differences are less than 1% between the two. If you want a “minimal” desktop experience, the Manjaro LXQT spin is the one to go for…

Having said the above, KDE has a lot of optional components like Magic Lamp, Wobbly Windows, fading pop-ups, Translucency, … so if you turn everything ON, yes, KDE will use more CPU and more RAM than XFCE…
